Aciclovir, indications, usage, dosage, contraindications & side effects, buying tips, price and reviews

Aciclovir is a medical treatment subject to prescription that is intended to reduce the pain caused by shingles, but also genital herpes.

Herpes is usually transmitted through sexual contact. The generic version of Aciclovir, Zovirax, operates in the same way. There is to date no treatment to cure herpes.

What is Aciclovir?

Actavis logoAciclovir is a treatment intended to relieve the pain caused by the herpes virus, as well as shingles. Cold sores can also be treated with Aciclovir. Developed by Actavis Laboratories and patented in 1979, the treatment aims primarily to treat diseases caused by the herpes virus. Genital herpes, cold sores and also chickenpox are many diseases that can be treated with Aciclovir.

The active substance, Aciclovir, can be used in two different ways. The first way is therapeutic, in order to combat the virus. the second way is precautionary. When used in a lower dosage, the treatment can indeed be used to prevent a potential risk. A key feature of this treatment is to increase immune defences. Patients with viral diseases such as STIs can also use the treatment. A major benefit of the treatment is its duration of use. Unlike other medical treatments that can be perceived as heavy, Aciclovir’s duration of use of is very short. Aciclovir is available in two forms: as a cream, or as a tablet. According to studies on patients treated with Aciclovir, treatment is very simple and comfortable to use. The very short delay in effectiveness might also be a reason why the treatment is praised by both patients and physicians.

Although the herpes virus cannot currently be cured, the antiviral medicine Aciclovir reduces the disease’s pain and leaves the virus in a passive mode, in a sleep state.

Aciclovir works by preventing the herpes cells from reproducing and multiplying, and therefore stops the duplication of these cells. By preventing the virus from spreading further into the body, Aciclovir also stops the healthy cells from becoming infected with herpes. When at work, the antiviral can influence the polymerase enzymes.

What are the advantages of buying Aciclovir?

Aciclovir in its 200mg and 800mg versions is a very popular medication in Europe for the treatment of the herpes virus. It is especially recommended because of its fast action, its simple use, and its increased efficiency. Among the main advantages we can quote:

  • rapid reduction in itching
  • decrease in pain and discomfort
  • limits the number of sores
  • available in different dosages
  • use as a preventative treatment

Doctors often prescribe Aciclovir to patients suffering from cold sores and genital herpes.

Aciclovir is a generic version of the drug Zovirax. It consists of the same active ingredients and produces exactly the same effect.

When a herpes outbreak occurs, Aciclovir helps speed up the healing process. It is also very effective in preventive action; that is to say, when the patient notices the appearance of the first signs of an outbreak, even before the blisters and wounds arise. The preventive application thus limits the intensity of attacks.

Herpes is one of the most commonly transmitted STIs in UK. This virus is characterised by the appearance of blisters and painful sores. Although in general transmission of the virus is associated with sexual contact, it is possible to transmit HSV-1 indirectly (usually associated with labial herpes) via sharing glasses or utensils. HSV-2 (usually associated with genital herpes) is usually only spread by sexual contact.

When the virus is in remission, it is not contagious. But it becomes especially contagious when signs of a herpes attack occur, and throughout the following period. In order not to infect others, it is advisable to avoid sexual contact until the affected area is fully healed.

Currently, there is no permanent cure for herpes, and once contracted, the virus remains present in the body of the infected person for life. Symptoms occur when the immune system is weakened (from illness or fatigue).

But although the virus does not disappear, the frequency and severity of symptoms decrease with age.

Treatment for HSV aims to accelerate the healing process and reverse reactivation of the virus. Aciclovir is an extremely effective treatment for herpes because it works quickly to relieve symptoms during the active stages of an outbreak, and prevent outbreaks at the other stages of the disease.

According to studies, patients consider the effectiveness of treatment to be 4 out of 5.

What is the active ingredient of Aciclovir?

The active ingredient of Aciclovir is a substance of the same name, belonging to the class of antiviral drugs called analogical guanosine and which was developed in the second half of the twentieth century. Today it is a very popular drug.

It contains the active ingredient Aciclovir

It contains the active ingredient Aciclovir

Aciclovir works by inhibiting the growth of viral cells, which attempt to divide and multiply upon reactivation of the herpes virus. When the infection restarts and tries to progress, it emerges with the materialisation of genital and oral blisters, or cold sores, depending on the strain of the virus.

To accelerate growth, the virus must convert an enzyme called DNA polymerase. Aciclovir inhibits this conversion process and limits the development of the virus. Once it has stopped the growth of the virus, the immune system is able to fight off the infection. This medicine may not permanently cure herpes, but it accelerates the disappearance of symptoms.

What is the dosage of the treatment?

Aciclovir should be taken at the onset of symptoms.

The dosage of treatment depends on the medical examination conducted by the doctor. Depending on the specific type of virus and severity of the patient’s symptoms, the doctor may prescribe different dosages.

Genital herpes & labial herpes: the doctor usually recommends taking 5 200mg tablets every day for 5 days.

As a preventive measure against herpes: the doctor recommends taking one 200mg tablet four times a day for six to twelve months.

Shingles treatment: the doctor recommends taking 800mg of Aciclovir (200mg, 4 times), 5 times a day for a full week.

Aciclovir can be taken before, during or after a meal, food does not influence its activity.
